Sorry that i can't agree with you. From what i have learned, decibel is
logarithmic. i think the formula is decibel = 10 log X where X is the ratio of
2 sound.

When you add 20Db to 20Db, you don't get 40Db but 23Db(i am not sure the
correct answer). But I know 20Db is 10 times louder than 10Db and 30Db is 100
times louder than 10Db.

Other than this, I enjoy what you wrote. :-)

regards.
